[0002] "Geological exploration" refers to the investigation and research activities of geological exploration and detection through various means and methods to determine the appropriate bearing layer, determine the foundation type according to the bearing capacity of the foundation of the bearing layer, and calculate the foundation parameters. Directional drilling is a method of drilling holes (wells) according to the trajectory required by the design using manual control and special drilling technology. The holes (wells) completed by this drilling technology are called directional holes (wells). The main advantages of directional drilling are: it can drill to the target layer more accurately, increase the oil and gas or groundwater production of a single well, and when cluster wells and multi-bottom wells are used, it can save land area, reduce the workload of relocating drilling equipment, save drilling workload and drilling engineering costs, etc.

[0003] During directional drilling, it is sometimes necessary to drill holes in rock walls, slopes, etc. To ensure the stability of the drilling process, the drilling equipment must first be positioned. The existing positioning process generally uses a drill rod to drill holes, and then fixes the drilling platform with anchor bolts, fixing screws, etc. During the drilling and fixing process, there is a certain gap between the drill rod and the drill hole, which causes the fixed structure to shake easily inside the drill hole, affecting the stable use of the drilling platform.

[0027] like Figure 1-6 As shown, a directional drilling device for geological exploration includes a drilling equipment body 1 and a drilling platform 2, a plurality of auxiliary positioning components are connected to the periphery of the drilling platform 2, the auxiliary positioning components include a positioning motor 3 and a positioning rod 4, a breakthrough opening 5 is opened in the middle and lower part of the positioning rod 4, a closing plate 6 is movably arranged on the inner side of the breakthrough opening 5, an adjusting screw 7 is arranged inside the positioning rod 4, and a limiting component is connected to the lower part of the adjusting screw 7. When the adjusting screw 7 rotates, the adjusting screw 7 drives the closing plate 6 to move away from the inner side of the breakthrough opening 5, and at the same time, the limiting component breaks outward through the breakthrough opening 5 to form a limiting waist.

[0028] The outer end of the limiting waist is a pointed end, and the limiting waist squeezes between the positioning rod 4 and the drill hole, thereby improving the pull-out resistance of the positioning rod 4 and ensuring the stable setting of the drilling platform 2.

[0029] like Figure 4 and Figure 6 As shown, a connecting cavity 8 is provided in the axial direction of the positioning rod 4, a circular arc-shaped limiting groove 9 is provided at the bottom of the connecting cavity 8, a connecting rod 10 is provided on the inner side of the closing plate 6, the lower end of the connecting rod 10 is slidably arranged in the limiting groove 9, a supporting spring 11 is provided inside the limiting groove 9, and an adjusting rope 12 is connected to the lower end of the connecting rod 10;

[0030] A rotatable connecting sleeve 13 is connected to the inner bottom of the connecting cavity 8 , the other end of the adjusting rope 12 is connected to the connecting sleeve 13 , and the lower end of the adjusting screw 7 and the connecting sleeve 13 are lockably connected.

[0031] The connecting sleeve 13 is rotationally connected to the connecting cavity 8 . When the connecting sleeve 13 is locked with the adjusting screw 7 , the adjusting screw 7 can drive the connecting sleeve 13 to rotate and reel in the adjusting rope 12 .

[0032] like Figure 4 and Figure 6 As shown, the inner ring of the connecting sleeve 13 is provided with a plurality of locking grooves 14, and the lower part of the adjusting screw 7 is provided with a plurality of accommodating cavities, the interior of which is connected with a reset spring and a limit ratchet 15, and the locking grooves 14 are used to accommodate the limit ratchet 15;

[0033] A plurality of electromagnets 16 are disposed inside the adjusting screw 7. When the electromagnets 16 are energized, they can attract the limit ratchet 15 so that the limit ratchet 15 is completely received into the accommodating cavity.

[0034] When the electromagnet 16 is energized, it can attract the limit ratchet 15 to release the lock between the adjusting screw 7 and the connecting sleeve 13. When the electromagnet 16 is de-energized, the limit ratchet pops out under the action of the reset spring to lock the adjusting screw 7 and the connecting sleeve 13.

[0035] like Figure 4 As shown, the upper end of the adjusting screw 7 is connected to the adjusting motor 17, the adjusting screw 7 is a forward and reverse threaded screw, and the upper and lower ends of the limit assembly are respectively connected to two sections of threads in opposite directions;

[0036] The limiting assembly includes a first connecting seat 18, a second connecting seat 19 and two external supporting parts connected between the first connecting seat 18 and the second connecting seat 19. The first connecting seat 18 and the second connecting seat 19 are respectively connected to two sections of the thread of the adjusting screw 7. When the adjusting screw 7 rotates, the first connecting seat 18 and the second connecting seat 19 are driven to move in opposite directions, so that the middle part of the external supporting part is pushed out in the direction away from the adjusting screw 7.

[0037] The first connecting seat 18 and the second connecting seat 19 are both threadedly connected to the adjusting screw 7. When the adjusting screw 7 rotates, it can drive the first connecting seat 18 to move downward and the second connecting seat 19 to move upward, so as to prop the outer support part outward.

[0038] like Figure 4 As shown, the outer support portion includes a first support rod 20 and a second support rod 21 that are rotatably connected. The outer end of the first support rod 20 is rotatably connected to the first connecting seat 18 , and the outer end of the second support rod 21 is rotatably connected to the second connecting seat 19 .

[0040] like Figure 4 As shown, an inclined bidirectional telescopic rod 22 is arranged inside the connection seat of the positioning motor 3, and a limiting hole is opened on the upper part of the positioning rod 4. When the bidirectional telescopic rod 22 is extended, the upper end of the bidirectional telescopic rod 22 extends into the limiting hole.

[0041] When the drilling is completed, the bidirectional telescopic rod 22 is extended to limit the positioning rod 4 and the surrounding rock and soil layers.

[0042] Directions:

[0043] When the device is used, after the drilling position is determined, the positioning motor 3 drives the positioning rod 4 to drill the hole, and the positioning rod 4 is used to position the drilling platform 2;

[0044] After the positioning rod 4 is drilled to the specified depth, the bidirectional telescopic rod 22 is extended, one end of the bidirectional telescopic rod 22 is inserted into the limiting hole, and the other end of the bidirectional telescopic rod 22 is pressed against the rock layer;

[0045] By operating the adjusting motor 17, the adjusting motor 17 drives the connecting sleeve 13 to rotate, and the adjusting rope 12 is wound up, and the adjusting rope 12 pulls the connecting rod 10 to move along the limiting groove 9, so that the closing plate 6 is moved away from the inner side of the breakthrough opening 5;

[0046] At the same time, as the adjusting screw 7 rotates, the adjusting screw 7 drives the first connecting seat 18 and the second connecting seat 19 to move toward each other, and the first support rod 20 and the second support rod 21 protrude outward through the breakthrough 5, forming a protruding limiting waist in the middle of the positioning rod 4. The limiting waist squeezes the positioning rod 4 and the drill hole to prevent the positioning rod 4 from being loosely fixed, thereby improving the stability of the drilling platform 2.
